British Airways cancelled nearly 550 flights between September 10 and 11, 2026, after a major outage at NATS, the UK’s air traffic control provider. The disruptions have affected thousands of passengers nationwide as UK airspace experienced significant operational failures.
Scope of the Disruption
The NATS outage caused around 2,000 flight cancellations across UK airports over the same period, impacting approximately 330,000 passengers. British Airways alone rebooked over 60,000 affected customers on alternative flights and offered free flight changes valid through September 13, 2026, for those who chose not to travel. The day before the outage, on September 9, British Airways operated close to 80%
of its planned schedule but still cancelled more than 190 flights.
Government and Regulatory Response
The UK Civil Aviation Authority (CAA) classified the disruption as ‘extraordinary circumstances,’ exempting airlines from compensating passengers for delays or cancellations caused by this event. Transport Secretary Heidi Alexander ordered the CAA to conduct an independent review of the NATS failure, with a report due within six months. She declared that the outage was not unavoidable. Prior to the outage, government ministers opposed a proposed amendment that would have required NATS to reimburse airlines for passenger compensation resulting from such failures.
Background of Repeated Failures
This incident marks the third major NATS airspace
management failure in three years, following previous outages including one in August 2023. NATS is a public-private partnership with 49% government ownership and 42% held by a consortium of airlines. Despite assurances after earlier outages, critics say NATS remains inadequate to manage UK air traffic reliably. Liberal Democrat MP Luke Taylor stated, “Following the third major failure of our airspace management in the past three years, it is imperative that this Bill is amended to include measures to stop that happening again. NATS is quite clearly not fit for purpose. We cannot suffer a major air traffic outage once a
year.”
Official Statements and Industry Reactions
British Airways said it was working to restore normal operations and thanked staff working additional shifts. NATS apologized to passengers, airlines, and airports, stating operations were stable and that a full investigation would determine the cause of the outage. Ryanair demanded the resignation of NATS CEO Martin Rolfe following the disruption that affected over 65,000 of its passengers and led to more than 50 flight cancellations. Wizz Air expressed extreme disappointment with the repeated NATS failures, emphasizing the ongoing impact on UK aviation networks.
Passenger Impact and Compensation
The cancellations by British Airways alone affected more than 85,000 customers. Overall, the NATS outage
led to the cancellation of about 2,000 flights and disrupted 330,000 passengers across UK airports. Despite this, passengers are unlikely to receive compensation due to the CAA’s classification of the incident as an extraordinary circumstance. British Airways offered free flight changes through September 13, 2026, to affected customers who no longer wished to travel.
Concerns Over UK Air Traffic Control Resilience
Repeated technical failures at NATS during peak travel periods have raised serious concerns about the resilience and reliability of the UK’s air traffic control infrastructure. The continued outages disrupt airlines and passengers across the country, undermining confidence in the system.
